Can this just be a function instead of an interface?

What about the skipSelfParent flag? (I think its purpose is to exclude "." and ".." when listing.) Perhaps instead of passing that flag into the parser, we could exclude "." and ".." here using the return value?

Can you add tests for the new functionality?

I've encountered some cases where the default parseLIST function fails to parse the outcome of a LIST command, despite getting useful data. This was encountered while communicating with an older FTP server.
Rather than attempting to cover all the types of output an FTP server could give in response to a LIST command, I've added the ability to specify a custom ListParser to handle these cases.
Here's a sample format i've seen that could not be handled, with fake fields:
